So I have this 500mb usb flash memory thing.

I connected it to my pc and I wanted to drag a file to my desktop or something simple like that.
And pooof, all the files from it suddenly go invisible.

I see they are still sitting on the usb because the 'properties' say its 488mb full but I don't see my files. Where are they/ how can this be fixed?

And I'd rather not format the thing if it is not absolutely necessary.


So once more.

My problem is: I cannot access the files on the memory stick. They take up space on it all right but I cannot see them.

Please please help me.
